Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If motor fuel blending component meeting ASTM fuel specifications
Fuel-grade alcohols classify under petroleum oils in Chapter 27.
If surface active preparation containing >30% alcohol content
Cleaning preparations with alcohols as active ingredients classify in Chapter 34.
If containing trace unsaturation or derived from unsaturated processes
Unsaturated acyclic alcohols fall under different subheading 2905.49.

Import Tips & Compliance
• Provide refractive index data (n20/D 1.396-1.398) to verify chemical identity
• Include end-use statement if for fuel applications to prevent Chapter 27 misclassification
• Use stainless steel containers to prevent reaction with iron during ocean transport
